What is star topology diagram?

Star Topology Diagram. In the star topology, all the computers connect with the help of a hub. This cable is called a central node, and all other nodes are connected using this central node. It is most popular on LAN networks as they are inexpensive and easy to install.

What is topology and star topology?

Star topology is a network topology in which each network component is physically connected to a central node such as a router, hub or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients. A star topology is also known as a star network.

What is topology diagram?

A network topology diagram is a visual representation of a network’s devices, connections, and paths, allowing you to picture how devices are interconnected and how they communicate with one another. The most common topologies are: Bus topology. All devices are connected by one central cable with two endpoints.

Is Lan a star topology?

A star network is a local area network (LAN) topology in which all nodes — personal computers (PCs), workstations or other devices — are directly connected to a common central computer that is often referred to as a hub.

What is the function of star topology?

The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub. Each host may thus communicate with all others by transmitting to, and receiving from, the hub.

What is a star topology and its advantages and disadvantages?

Advantages and disadvantages of a star network it is expensive to install as this type of network uses the most cable (network cable is expensive) extra hardware is required (hubs or switches) which adds to cost. if a hub or switch fails, all the devices connected to it will have no network connection.

What is star topology Javatpoint?

Star topology is an arrangement of the network in which every node is connected to the central hub, switch or a central computer. The central computer is known as a server, and the peripheral devices attached to the server are known as clients.

What is the example of star topology?

So, we connect our laptops, tablet PCs and Smartphones to the Wireless Modem for accessing the Internet. Hence, all our devices connect to a single central device known as Hub. So, this is probably the best Example of Star Topology.

What is meant by topology?

In networking, topology refers to the layout of a computer network. Topology can be described either physically or logically. Physical topology means the placement of the elements of the network, including the location of the devices or the layout of the cables.

What is topology draw and explain any two types of topology?

There are two types of network topologies: physical and logical. Physical topology emphasizes the physical layout of the connected devices and nodes, while the logical topology focuses on the pattern of data transfer between network nodes.

What is star topology and features?

The Star Topology (Hierarchical) In a star topology, computers aren’t connected to one another but are all connected to a central hub or switch. Characteristics of a star topology are as follows: ■ All cables run to a central connection point.

What is the best topology for LAN?

Best topology for LAN. The topology is made up of LAN workstations, also called nodes. The lines between nodes represent cables. Junction boxes are used to interconnect the cables. Theoretically, any kind of cable medium could be wired together to create an infinite variety of network layouts.

What are the advantages and disadvantages of star topology?

Advantage of star topology: With the star topology, if one cable of device goes down, the rest of the network is not affected (fault tolerance). Disadvantage of star topology: However, because management of communication is centralized, if the main switch or hub goes down the whole network goes down.

What are the characteristics of star topology?

Star topology. Star topology in use in a network. A Star network is one of the most common computer network topologies. In star topology, every host is connected to a central hub. In its simplest form one central hub acts as a conduit to transmit messages. A star network is an implementation of a spoke–hub distribution paradigm in computer networks.

What are the types of Lan?

A WAN is a type of Local Area Network (LAN). A LAN is a private network that typically is made up of a well-connected, reliable, and fast network connection. Alternatives on the LAN framework include CANs, MANs, and WANs.
